[TABAC] étudeIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Introduction:
Many carbonyls are produced from the combustion of tobacco products and many of these carbonyls are harmful or potentially harmful constituents of mainstream cigarette smoke.
One carbonyl of particular interest is acrolein, which is formed from the incomplete combustion of organic matter and the most significant contributor to non-cancer respiratory effects from cigarette smoke. Sheet-wrapped cigars, also known as “little cigars,” are a type of tobacco products that have not been extensively investigated in literature.
Methods:
This study uses standard cigarette testing protocols to determine the acrolein yields from sheet-wrapped cigars. Sheet-wrapped cigar and cigarette products were tested by derivatizing the mainstream smoke with 2,4-dinitrophenylhydrazine (DNPH) solution and then quantifying the derivatives using conventional analytical systems.
Results:
The results demonstrate that sheet-wrapped cigars can be tested for acrolein yields in mainstream smoke using the same methods used for the evaluation of cigarettes. The variability in the sheet-wrapped cigars and cigarettes under the International Organization for Standardization smoking regimen is statistically similar at the 95% confidence interval; however, increased variability is observed for sheet-wrapped cigar products under the Health Canada Intense (CI) smoking regimen.
Conclusion: The amount of acrolein released by smoking sheet-wrapped cigars can be measured using standard smoking regimen currently used for cigarettes. The sheet-wrapped cigars were determined to yield similar quantity of acrolein from commercial cigarette products using two standard smoking regimens.
Implications:
This article reports on the measured quantity of acrolein from 15 commercial sheetwrapped cigars using a validated standard smoking test method that derivatizes acrolein in the
mainstream smoke with DNPH solution, and uses Liquid Chromatography/Ultra-Violet Detection (LC/UV) for separation and detection. These acrolein yields were similar to the levels found in the smoke from 35 commercial cigarette products measured in the same manner. Although sheetwrapped cigar data were slightly more variable than those found for the cigarette data, this article reports that the production of acrolein is similar to cigarettes. The results demonstrate that sheet-wrapped cigars can be tested for acrolein yields in mainstream smoke using the same methods used for the evaluation of cigarettes.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9705 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] tabagisme:aspect psychologique:image de la cigaretteIndex. décimale : TA 5.4 Prévention et médias Résumé : Introduction:
Instagram is a popular social networking platform for sharing photos with a large proportion of youth and young adult users. We aim to identify key features in anti-vaping Instagram image posts associated with high social media user engagement by artificial intelligence.
Aims and Methods:
We collected 8972 anti-vaping Instagram image posts and hand-coded 2200 Instagram images to identify nine image features such as warning signs and person-shown vaping. We utilized a deep-learning model, the OpenAI: contrastive language-image pretraining with ViT-B/32 as the backbone and a 5-fold cross-validation model evaluation, to extract similar features from the Instagram image and further trained logistic regression models for multilabel classification. Latent Dirichlet Allocation model and Valence Aware Dictionary and sEntiment Reasoner were used to extract the topics and sentiment from the captions. Negative binomial regression models were applied to identify features associated with the likes and comments count of posts.
Results:
Several features identified in anti-vaping Instagram image posts were significantly associated with high social media user engagement (likes or comments), such as educational warnings and warning signs. Instagram posts with captions about health risks associated with vaping received significantly more likes or comments than those about help quitting smoking or vaping. Compared to the model based on 2200 handcoded Instagram image posts, more significant features have been identified from 8972 AI-labeled Instagram image posts.
Conclusion:
Features identified from anti-vaping Instagram image posts will provide a potentially effective way to communicate with the public about the health effects of e-cigarette use.
Implications:
Considering the increasing popularity of social media and the current vaping epidemic, especially among youth and young adults, it becomes necessary to understand e-cigarette-related content on social media. Although pro-vaping messages dominate social media, antivaping messages are limited and often have low user engagement. Using advanced deep-learning and statistical models, we identified severalfeatures in anti-vaping Instagram image posts significantly associated with high user engagement. Our findings provide a potential approach to effectively communicate with the public about the health risks of vaping to protect public health.En ligne : https://doi.org/10.1093/ntr/ntad189 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10239 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

INTRODUCTION:
A paucity of data exists regarding the safety and effectiveness of combination treatment with varenicline and nicotine replacement therapy (NRT).
METHODS:
We reviewed the clinical experience of two groups of cigarette smokers enrolled in a residential tobacco treatment program: (a) patients receiving combination treatment with varenicline and NRT (N = 104) and (b) usual-care patients receiving treatment before the release of varenicline (N = 135).
RESULTS:
Demographic characteristics were similar between the two groups. Among smokers receiving varenicline and NRT, 71% used the nicotine patch with a mean dose of 32 mg/day (SD = 14) and 73% used at least two types of NRT. Adverse events were experienced by 39% (95% CI = 31%-49%) of patients receiving varenicline and NRT and by 59% (95% CI = 51%-67%) of usual-care patients during the residential program. A total of five patients (5%) discontinued varenicline due to adverse events, compared with one patient in the usual-care group. We did not observe a significant difference in the 30-day point prevalence smoking abstinence rate at 6 months between patients treated with varenicline and NRT (54%; 95% CI = 44%-64%) and usual-care patients (59%; 95% CI = 50%-66%).
DISCUSSION:
Our findings suggest that combination therapy with varenicline and NRT is safe and well tolerated among patients in a residential tobacco treatment program.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=7950 Exemplaires (1)

Systematic assessments of Motivational Interviewing (MI) in smoking behavior have been rare to date. This study aimed to determine whether an integrated approach, involving staff training in MI techniques, was sufficient to affect change in smoking status or intensity in low-income pregnant and postpartum women.
Methods:
Overall, 500 consecutive smokers were recruited at first prenatal visit to public antenatal clinics. Following staff training,500 more were recruited (intervention group). Data were recorded at 28–32 weeks gestation, after birth, at 3–4 and 7–9 months postpartum.The primary outcome measure was self-reported continued abstinence from smoking verified by urinary cotinine analysis.
Changes in smoking intensity were also measured.
Results:
There was no significant difference in the proportion of smokers in the intervention and control groups who reported stopping smoking at 28–32 weeks gestation (8.2% vs. 8.8%; p = .73), 1 week after birth (8.6% vs. 11.4%; p = .14), 3–4 months after birth (5.8% vs. 4.8%; p = .48), or 7–9 months after birth (5.2% vs. 4.0%; p = .36). Although more cases were nonsmoking at the second visit, 14.8% [95% CI = 11.8–18.5] vs. 13.1% controls [95% CI = 10.3–16.6], this was not statistically significant.
Conclusions:
MI delivered at a number of time points during pregnancy and up to 9 months postpartum failed to affect quit rates. It may have had a small effect in preventing relapse among spontaneous quitters in late pregnancy though the validity of this remains uncertain.En ligne : https://doi.org/10.1093/ntr/nts225 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9693 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] sevrage tabagiqueIndex. décimale : TA 3.2.2.7 Grossesse et fœtus Résumé : Introduction:
The purpose of this study was to use data from controlled trials to examine whether smoking cessation increases breastfeeding duration. Correlational studies have confirmedassociations between smoking status and breastfeeding duration, but whether smoking cessation increases breastfeeding duration has not been established.
Methods:
Participants ( N = 158) were smokers at the start of prenatal care who participated in controlled trials on smoking cessation. Women were assigned to either an incentive-based intervention wherein they earned vouchers exchangeable for retail items by abstaining from smoking or a control condition where they received comparable vouchers independent of smoking status. Treatments were provided antepartum through 12-week postpartum. Maternal reports of breastfeeding collected at 2-,
4-, 8-, 12-, and 24-week postpartum were compared between treatment conditions. Whether women were exclusively breastfeeding was not investigated.
Results:
The incentive-based treatment signifi cantly increased breastfeeding duration compared with rates observed among women receiving the control treatment, with signifi cant differences between treatment conditions observed at 8-week (41% vs. 26%; odds ratio [ OR ] = 2.7, 95% CI = 1.3– 5.6, p = .01) and 12-week
(35% vs. 17%; OR = 3.4, 95% CI = 1.5– 7.6, p = .002) postpartum. No significant treatment effects on breastfeeding were observed at other assessments. Changes in smoking status mediated the effects of treatment condition on breastfeeding duration.
Conclusions:
These results provide evidence from controlled studies that smoking cessation increases breastfeeding duration, which, to our knowledge, has not been previously reportedEn ligne : https://doi.org/10.1093%2Fntr%2Fntq031 Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9576 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] prévention:campagne:campagne médiatique:internetIndex. décimale : TA 1.1.1 Cigarettes (« normales », électroniques, aromatisées,…) Résumé : Introduction:
Over the past decade, youth e-cigarette use has risen exponentially. At the same time, digital media use increased markedly while the use of traditional broadcast TV declined. In response, the U.S. Food and Drug Administration’s The Real Cost public education campaign shifted to communicating the harms of e-cigarette via primarily digital and social platforms. This study evaluated longitudinal associations between exposure to campaign advertisements and changes in campaign-specific beliefs among US youth.
Methods:
A nationally representative longitudinal cohort of youth (aged 11–16 years at baseline) was surveyed five times. Building on earlier work, we analyzed data from the last three waves (April–July 2020; January–April 2021; and August–October 2021; N = 2625). We assessed self-reported exposure to six ads and agreement with 11 beliefs that were each targeted by one or more ads. Eleven weighted panel regression models assessed whether ad exposure predicted changes in campaign-specific beliefs over time.
Results:
We observed significant associations between ad exposure and increases in at least one campaign-specific belief for five of the six ads. Across the 11 beliefs, we observed associations between increased exposure and increases in 6 beliefs related to e-cigarettes and toxic metals, lung damage, dangerous ingredients, anxiety, cigarette use, and disappointing important people.
Conclusions: We found evidence that self-reported exposure to this digital and social media campaign was successful at influencing youth, providing support for the effectiveness of the campaign’s adaption to address youth’s changes in tobacco and media use habits.
Implications:
The Food and Drug Administration’s The Real Cost public education campaign educates youth about the dangers of e-cigarette use. This study evaluates longitudinal associations between exposure to The Real Cost’s advertisements and changes in campaign-specific beliefs among youth. Considering evolving trends in youth media consumption, the campaign adapted its media approach to increase delivery across digital and social media platforms. Our findings indicate that the campaign reached its intended audience and increased youth beliefs around the harm of e-cigarettes and the consequences of e-cigarette use, offering evidence for the effectiveness of digital and social media

[TABAC] tabagisme:évaluation du tabagisme:marqueurIndex. décimale : TA 6.2.3.2 Autres produits Résumé : NTRODUCTION:
It has been reported that adult smokers (AS) may be considering smokeless tobacco products as an alternative to smoking. The objective of this study was to evaluate the change in exposure in AS using Marlboro snus (MSNUS) (a tobacco pouch product in test market in June 2007).
METHODS:
AS were randomized into the following groups--CS: subjects (n = 30) continue smoking their own brand; DU: subjects (n = 60) reduced their daily cigarette consumption by >or=50% and were allowed to use MSNUS; SN: subjects (n = 15) stopped smoking their cigarettes but were allowed to use MSNUS; NT: subjects (n = 15) were not allowed to use any tobacco products for the entire duration of the 8-day study. Biomarkers of smoke exposure (BOE) measured at baseline and postbaseline were 24-hr urinary excretion of metabolites of N-nitrosamines, nicotine (urine and plasma), aromatic amines, benzene, and polycyclic aromatic hydrocarbon; urine mutagenicity; and carboxyhemoglobin at various timepoints.
RESULTS:
Statistically significant (p < .05) reductions in all the urinary BOE were observed in the DU group compared with the CS group. After correcting for the residual effect, a proportionate reduction (approximately 50%) in most of the biomarkers was observed. Even larger reductions, similar to the NT group, were observed in the SN group.
DISCUSSION:
The proportionate reduction in exposure when reducing the number of cigarettes by 50% and using MSNUS, under the consumption patterns observed, suggest that the AS did not appear to alter their smoking behavior. The added exposure from MSNUS usage in this group was minimal. The AS sustained substantial reductions in exposure when using MSNUS exclusively.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=7957 Exemplaires (1)

Social media platforms are promising to provide smoking cessation support. This study aimed to identify baseline factors associated with cigarette smoking abstinence among young adult smokers enrolled in a real-world social media-based smoking cessation program.
Aims and Methods:
We analyzed data from young adult smokers (aged 18–30 years) participating in a publicly available Facebook-based smoking cessation program serving the San Francisco Bay Area. The analytic sample consisted of 248 participants who completed both the baseline and follow-up surveys at 3 months. Multivariable logistic regression analysis determined baseline factors significantly associated with self-reported 7-day cigarette smoking abstinence at 3 months.
Results:
Participants were race/ethnically diverse, well-educated, and 47.6% reported LGB + sexual identity. Those who reported dual use of cigarettes and e-cigarettes in the past 30 days (vs. cigarette use only), current alcohol users (vs. non-users), and those aged 25–30 years (vs.18–24 years) were significantly less likely to report 7-day abstinence at 3 months. Non-daily smokers (vs. daily smokers) and those with high desire to quit smoking (vs. low to moderate desire) were more likely to report abstinence. Results also showed reduction in the percentage of e-cigarette and other tobacco product use among participants.
Conclusions:
Social media interventions may be more effective for young adult non-daily smokers and those with high desire to quit smoking. Smoking cessation programs may help reduce use of other tobacco products among treatment-seeking smokers. Smoking cessation interventions for young adults need to explicitly address dual use of cigarettes and e-cigarettes and use of alcohol.
Implications:
Findings of this study highlight the need for future interventions to address dual use of cigarettes and e-cigarettes and use of alcohol to improve cigarette smoking abstinence outcomes. The reduction in the use of other tobacco products among program participants indicates that social media smoking cessation programs may exert a broader positive influence on overall tobacco consumption. The large number of LGB+ smokers participating in the program suggests social media is a promising cessation channel for this hard-to-reach group, warranting further study.En ligne : https://doi.org/10.1093/ntr/ntad170 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10242 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

[TABAC] tabagisme:risque:perception du risqueIndex. décimale : TA 6.2.1 Simples conseils, avis Résumé : Because quitting smoking is clearly linked to preventing health problems such as lung cancer, research on health message framing based on prospect theory suggests that gain-framed messages (i.e., emphasizing the benefits of quitting smoking) would be more persuasive in promoting cessation than loss-framed messages (i.e., emphasizing the costs of continuing to smoke). However, because women tend to anticipate greater perceived risk from quitting smoking than men, this may affect how receptive they are to specific message framing interventions. Data from 249 participants (129 females, 120 males) in a clinical trial of message framing for smoking cessation with bupropion were used to examine how gender differences in perceptions of the risks associated with quitting influence the effects of framed interventions using number of days to smoking relapse as the criterion. Perceived risk of quitting scores were dichotomized using a median split for the entire sample. Women reported a higher perceived risk of cessation than men. Participants who anticipated high risks associated with quitting smoking reported fewer days to relapse. Further, females in the gain-framed condition who reported low perceived risks of cessation had a greater number of days to relapse, as opposed to females in the loss-framed condition. These findings suggest that message framing interventions for smoking cessation should consider the influence of gender and risk perceptions associated with quitting on the effectiveness of framed interventions.

[TABAC] tabagisme:risque:perception du risqueIndex. décimale : TA 3.2 Effets du tabagisme actif Résumé : Introduction:
Few studies have examined the perceptions of risk of LCC smoking among cigarette smokers, which is important for expanding regulatory policies and developing prevention programs. We examined current cigarette smokers’ perceived harm of LCC smoking, and determined whether these perceptions were associated with susceptibility and intention to continue smoking LCCs.
Methods: Data were from the 2014 Tobacco Products and Risk Perceptions Survey of a probability sample of 5717 US adults. Data were analyzed for a subsample of 1191 current cigarette smokers who were stratified into three groups: 1) dual current cigarette smokers who had ever used LCCs, 2) current smokers susceptible to LCC smoking, and 3) current smokers who were not susceptible to LCC smoking.
Results:
Overall, 47.2% of participants were dual smokers, 12.7% were susceptible to LCC smoking, and 40.1% were not susceptible. Perceptions of risk of LCCs varied across the groups. Dual smokers were more likely to perceive that daily LCC smoking is ‘very risky’ (OR = 1.64, 95% CI = 1.08, 2.41) while occasional LCC smoking is only ‘somewhat risky’ (OR = 1.71, 95% CI = 1.02, 2.87). Of the dual smokers, 20.7% intended to continue smoking LCCs in the future. Perceptions of addiction and risk of daily LCC smoking significantly predicted intention to continue LCC smoking. Addiction perceptions also significantly predicted susceptibility to initiate LCC smoking.
Conclusions:
Perceptions about harms from and addiction to LCCs could predict future LCC smoking. Health communication campaigns need to address the harms of LCCs.
Implications
Our data suggest that perceptions of risk about the addictiveness of LCCs and frequency of use are important determinants of the LCC smoking susceptibility among some cigarette smokers and intended continued use among cigarette smokers with a history of LCC use. Health communication campaigns should address misperceptions related to LCCs.En ligne : https://doi.org/10.1093/ntr/ntw244 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9704 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

Instagram and TikTok, video-based social media platforms popular among adolescents, contain tobacco-related content despite the platforms’ policies prohibiting substance-related posts. Prior research identified themes in e-cigarette-related social media posts using qualitative or text-based machine learning methods. We developed an image-based computer vision model to identify e-cigarette products in social media images and videos.
Methods:
We created a dataset of 6,999 Instagram images labeled for 8 object classes: mod or pod devices, e-juice containers, packaging boxes, nicotine warning labels, e-juice flavors, e-cigarette brand names, and smoke clouds. We trained a DyHead object detection model using a Swin-Large backbone, evaluated the model’s performance on 20 Instagram and TikTok videos, and applied the model to 14,072 e-cigarette-related promotional TikTok videos (2019-2022; 10,276,485 frames).
Results:
The model achieved the following mean average precision scores on the image test set: e-juice container: 0.89; pod device: 0.67; mod device: 0.54; packaging box: 0.84; nicotine warning label: 0.86; e-cigarette brand name: 0.71; e-juice flavor name: 0.89; and smoke cloud: 0.46. The largest number of TikTok videos – 9,091 (65%) - contained smoke clouds, followed by mod and pod devices detected in 6,667 (47%) and 5,949 (42%) videos respectively. Prevalence of nicotine warning labels was the lowest, detected in 980 videos (7%).
Conclusions:
Deep learning-based object detection technology enables automated analysis of visual posts on social media. Our computer vision model can detect the presence of e-cigarettes products in images and videos, providing valuable surveillance data for tobacco regulatory scienc.
Implications :
● Prior research identified themes in e-cigarette-related social media posts using qualitative or text-based machine learning methods. We developed an image-based computer vision model to identify e-cigarette products in social media images and videos.
● We trained a DyHead object detection model using a Swin-Large backbone, evaluated the model’s performance on 20 Instagram and TikTok videos featuring at least two e-cigarette objects, and applied the model to 14,072 e-cigarette-related promotional TikTok videos (2019-2022; 10,276,485 frames).
● The deep learning model can be used for automated, scalable surveillance of image- and video-based e-cigarette-related promotional content on social media, providing valuable data for tobacco regulatory science. Social media platforms could use computer vision to identify tobacco-related imagery and remove it promptly, which could reduce adolescents’ exposure to tobacco content online.Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=10283 Aucun avis, veuillez vous identifier pour ajouter le vôtre !

lthough the popularity of small cigar brands that resemble cigarettes, including both little cigars (LC) and filtered cigars (FC), has been on the rise, little is known about the delivery
of nicotine from these products. Our objective was to determine the nicotine yields of small cigars in comparison to cigarettes.
Methods:
Nicotine yields from LC, FC, and 3R4F and 1R6F research cigarettes were determined from mainstream smoke generated on a smoking machine under the International Organization of
Standardization (ISO) and Canadian Intense (CI) methods. Market characteristics (price and package label) and physical features (filter ventilation, product weight and filter weight, product length, and diameter) were also determined for eight brands of small cigars.
Results:
Nicotine yields in small cigars averaged 1.24 and 3.49 mg/unit on ISO and CI regimens, respectively, compared with 0.73 and 2.35 mg/unit, respectively, for the research cigarettes.
Nicotine yields per puff were similar between small cigars and cigarettes. We also found that FC did not differ from LC in nicotine yields. FC and LC differ from each other in many physical design features (unit weight, filter weight, and filter length), but are similar in others (unit length, diameter,
and filter ventilation).
Conclusions:
Nicotine delivery from small cigars is similar to or greater than that from cigarettes. Thus, for future research and regulatory purposes, standard definitions need to be developed for
small cigars, and FC and LC should be evaluated as separate entities. Implications: Small cigars are similar to cigarettes in their design and use. Although nicotine yields
per puff were similar between products, small cigars delivered substantially higher amounts of nicotine per unit than cigarettes. These findings support the growing body of evidence to justify regulating all small cigars, including LC and FC in a similar fashion as cigarettesEn ligne : https://doi.org/10.1093/ntr/ntx220 Format de la ressource électronique : Article en ligne Permalink : https://biblio.fares.be/opac_css/index.php?lvl=notice_display&id=9707 Aucun avis, veuillez vous identifier pour ajouter le vôtre !
